DETACHABLE BEARING FOR THE SPINDLES OF SPINNING MACHINES.

Application filed November 3, 1922. Serial No. 598,961.

To all whom it may concern:

Be it known that I, JoHANN JACOB KEY- SER, a citizen of Switzerland, and resident of Aaran, Switzerland, have invented a new and useful Detachable Bearing for the Spindles of Spinning Machines, of which the following is a specification.

The invention relates to detachable bear ings for the spindles of spinning machines.

Hithereto the removal of a spindle from its casing for the purpose of cleaning or the like was only possible when the several parts of the bearing had been taken apart, and when then the bearing is to be reassembled a careful adjustment must be made in order to secure a faultless travel of the spindles. The reason for this disadvantageous manipulation is the fact that the spindle rests in bearings on a stationary casing or frame and it was therefore necessary for the removal of the spindle at first to unscrew the bearing cover and the parts above it, whereupon the spindle could be lifted or removed with its bearings. Furthermore it was also necesary to remove the cam wheel from the cam or screw threads of the spindle. I

According to the present invention the spindle is mounted with its upper bearing in the cover of the casing and the worm of the spindle extends to the lower end of the spindle, in such a manner that after unscrewing the cover of the casing the spindle with its upper bearing can be lifted or drawn upwardly without the necessity to unscrew or remove other parts of the bearing.

This easy removal of the spindle is essential when ball bearings are provided which require from time to time a careful plfianing by washing out with benzine or the The accompanying drawing illustrates the invention, partly in section.

- The spindle 1 is mounted in the casing 2 fixed in suitable manner on the rail or a part of the spinning machine. The lower end of the spindle has a reduced portion or a pin 4 running in a ball bearing 3 secured in suitable manner on the lower end of the casing. The spindle is provided with a worm 6, the core of which is equal or greater than the diameter of the pin 4. With this worm 6 a worm-wheel 15 is in engagement entering in a recess of the casing, as shown.

The spindle 1 runs with its upper part in a ball bearing 7, arranged in a cup 8 filled with oil. This'cup 8 is secured on the cover 9 of the casing and supported by springs 10. The cover 9 is screwed into the casing 2 or may be fixed on this easing by means of screws or the like. In order to prevent the entrance of dust or the like the cover 9 is provided with an upwardly projecting sleeve 12 surmounted by a downwardly projecting gland 13 of a cap 14 secured on-the spindle 1.

When the spindle 1 is to be lifted or drawn out from the casing it is only necessary to unscrew the cover 9 and the latter together withthe spindle and theupper ball bearing may then be taken out by screwing up the worm 6 from the worm-wheel.

The insertion of the spindle is performed in the reversed manner by screwing down the worm 6 into the worm-wheel.

The arrangement described is essential when the upper ball bearing 7 is supported by compensation springs.

Having now described my invention, what I claim and desire to secure by Letters Patent, is a In a detachable bearing for the spindles of spinning machines, the combination of a casing and a spindle, a cover for this casing, a worm on the spindle and extending to the end of the said spindle, a wormwheel in engagement with the worm, a bearing in the lower part of the casing and in which the spindle enters with a reduced portion, a second bearing in the cover of the casing, substantially as described. I

In testimony whereof I aifix my signature in the presence of two witnesses.
